The MicroImage PG311/PG314 series of
pattern generators are for applications to display custom designed
screen. The PG311/PG314 units will
overlay the pattern or patterns on top of the video signal
provided to the input of the device. The PG311 can be
factory programmed with one unique pattern, while the PG314
can hold up to four patterns and switch between them.
The pattern image files can be sent to the factory as a bit
mapped file, in GIF, TIFF, BMP and other formats. JPEG is
not an acceptable format. The resolution can be either
320x240x1 or 640x480x1 for NTSC. For PAL, the resolution is
384x288 or 768x576 (only up to 512 of the 576 lines
addressable in PAL).
The units have
switches for Pattern Display on/off, Power on/off and a
rotary control to change the brightness of the pattern. The
PG314 also has individual switches to select each pattern.
Units are available to function with a variety of video
signals. The PG311/PG314 work with composite, B&W and
S-Video signals. The PG311N and PG314N work with the
